Description

technical field [0001] The invention relates to a thermal field of a polycrystalline ingot casting furnace. Background technique [0002] With the development of the economy and the progress of society, people put forward higher and higher requirements for energy, and finding new energy has become an urgent issue facing mankind. The existing sources of electric energy mainly include thermal power, hydropower and nuclear power, but these three kinds of energy have different degrees of impact on the environment we depend on for survival, and there are various hidden dangers in installation. Solar energy is an inexhaustible renewable energy source for human beings, and it is also a clean energy source. It is rich in resources, can be used for free, and does not require transportation. An era of saving energy and reducing pollution. Crystalline silicon solar photovoltaic power generation is currently the fastest-growing, most dynamic and potential application field. In the man...

Problems solved by technology

[0004] The purpose of the present invention is to provide a polycrystalline ingot casting furnace thermal field, which solves the problem that the silicon liquid overflow caused by the crucible rupture in the ingot casting process may cause the furnace cavity to melt through if it is not detected in time, and has the advantages of improving the yield of the crystal ingot , improving crystal quality, reducing energy consumption, and high safety. The invention satisfies the uniform and symmetrical structure of the heat insulation cage and the furnace body, improves the eccentricity of the thermal field, and not only can produce polycrystalline silicon ingots with high yields, but also the ingot quality and The energy consumption of ingot casting is better than that of ordinary ingot furnace equipment, and it can effectively guarantee the safety of equipment and personnel
